IMPROVEMENT IN FEED-REGULATOR EOE SPINNING MACHINES.

TQ ALL WHOM IT MAY :CONCERN:

Be it known that I, CHRISTOPHER Hunnsenasr, of Brooklyn, in the countyof Kings, and State of New York, have invented a. certain nexv anduseful-Improvement on Regulators to Jennies for Spinning Rope-Yarns, orother apparatus controlling the feed to the drawing-rolls of spinningframes, of which the following is a vfulhclear, and exact description,reference being had to the accompanying drawing, forming part of thisspecification, and in which- Figure l represents a plan of a` regulatingapparatus constructed according to my improvement.

Figure-2, a sectional elevation of the same; and y t Figure 3 asectional elevation of certain details used to carry out myinventionrdetached and taken `as 'indicated by the une a' e in ng. 2. y

Like letters indicate likel parts throughout the severa-l figures. l y pvThe nature of my invention consists in a combination, with suitableclutchmechanism under control of the dravving-rolls, of' wheels ofdifferent diameters arranged on a primary and secondary shaft, the oneof which is hung loose on its shaft, and geared theterth bya pawl andratchet to vary the velocity-given to the gill-bars, without stoppage orlost motion in making the changes te suit variationsin thickness of thesliver; and said invention also consists in a 4novel combinationV offast and loose wheels, as described, with clutch levers so operated bythe dra'wing-rolls-as that only the fast motion maybe put in gear, orboth fast anu slow motions thrown out simultaneously bythe opening andclosing of the drawing-rolls. y i

Referring to the accompanying drawing, A represents the drawing-rolls,geared together by pnions B,

driven by any suitable mechanism, and serving to pass the sliver from4the gill-bars through orover the regulatorA to the yer. The one ofthese rolls A has its shaft hungin levers or arms hinged as at a, andcarrying at their ,outer ends a rod, connected with a lowercross-ibanic.C is the running or cli-ivingfshaft of the regulator,

carrying, so as to rotate with it, clutches D D', that, when thrown'intoaction, `gear with-loose sliding clutches E E', having secured to them awheel and pinion F F', which gear, the one (Wheel F) with a spur-wheel,G, fast to ansecondary shaft, H, and the other (pinion F) withaspur-wheel, G,1loose on said shaft, vbut geared therewith under certaincircumstances, as hereinafter explained, by means of'a ratchet-Wheel, K,fast to the shaft H and spring-dog or pawl L, connected with the wheelG. This secondary shaftH serves by pulley and belt, or otherwise, togive motion to the gill-bars which feed the-material to thedrawing-rolls. i When the wheel F is the driver t0 the spur-'wheel G, acomparatively rapid motion is given to the secondary shaft H, and of aconsequence to the gill-bars, producing a fast feed of the sliverthrough the drawing-rolls to 'the iyer, which actions given on thesliver being thinner than it should be to pass to the iyor. y On theother hand, when the pinion .Ff is the ldriver-,of the shaft II throughthewheel G', which'action occurs when the sliver is of. the properthickness, then the motion to the gill-bars and feed through thedrawing-rolls A is slower. By these means an Vc cluality of feed isestablished to the flyer, which regula-ting action is effected by therise or fall, accordingV to the thickness of the passing sliver, Vof thedrawing-roll or rolls, say the roll connected with-thc levers thatearrythe rod b und cross-bare; said cross-bar acting upon pinsel (ZY, of armse Vc,branehingfrom elutchleversI I',

-lthnt have a'tend'e'nc'y, bytmeans ofa connecting spring, J, to' throwthe sliding clutches E Einto gear with the clutches D'D of the wheel andpinion F F', In ordinary action, that is, when the sliver passingthrough the drawing-rolls is of the proper thickness, the rolls areseparated only tothe necessary extent to cause the crossbar c,whichiaetsprimarily on the vbar c `of the. clutch lever I, tothrow out of'gear thesliding clutch D with the clutch E of the wheel F. Underthese-circumstances,'and there being no lift on the'pinid the lever 1keeps inrgearthe-s'liding clutch D with the clutch E of thepinion-F,that accordingly'becoines the driver through thefwheel G of thefeed-driving secondary shaft H. Should the sliver, however, passingthrough the drawingl rolls, be thinner or finer than is proper, thenlift being taken off the pin d, the springJ causes the clutch'D to geartvith the clutchE of the -vvlrcel F, which through. the wheel G becomesthe driver of the secondary shaft H, by-ca`using it tor'un faster thanthe pinion F', and wheel Gr serves to operate it; the wheel G slippingon its shaftl by reason of 'itsconneetion therewith through the pawl Land ratchet-wheel K, said wheel, however, keeping in driving-gearthrough the pinion Ff', clutch E', 'and sliding clutch D",with therunning or drivingshaft C, so that on a proper thickness of sliver againpassing through 'the drawing-rolls, the speed of the gillbars and feedis slackened by lift on the arm e throwing the clutch E out of gear, andwithoutstoppnge'or any lost motion the pinion F' made theV driver of thesecondary or gill-har operating shaft at aslower velocity. Thisavoidance of any temporary stoppage or lost motion is highly important,and is secured by the gear of the pinion F' with the shaft, both whensaid pinion acts as the driver and when the wheel F is such, the gear ofthe wheel-G' with the shaft H by pawl and ratchet accomplishingthis,-irr'espective of any special onprecise clutch gear, which may beasrepresented, and connected with the drawing-rolls as described, orotherwise, th'ese i.

latter means being capable of great variation. Onthe sliver passingthrough the drawing-rolls being'too thick or coarse for the flyer, oranything unusual occurring to unduly open said rolls, then the bar c is.caused to lift both upon the primary pin Z and 'secondary pin d', so asto throw both clutches D D' out of gear', which stops the motion of thesecondary shaft I-I, and, as a consequence, of the gill-bars and feedtothe drawing-rollgand which gives an opportunity to remove the obstacleor rectify the feed What I claim as my invention, and desire to secureby Imtters Patent, is

i la The combination with a clutch or other mechanism, controlled by thedrawing-rolls, and serving to throw in or out of gear-with thedriving-shaft C, wheels or pinions F F' of the secondary orrgill-baroperating shaft ,H 'having gear G G', the one of which is eonnectedwithits shaft by pawl and 'ratchet L K, for operation in connection with thegear of the driving-snaft C, toV give afnst orslow motion to theVgill-bars, substantially :1s specified.

v 2. The' combination of the fast wheel Gr and loose wheelG', with itspawl and ratchet L K, loose wheel and piniouF F', with their clutches EEQU) D', and clutch arms or levers I I', so arranged and operated bymechanism connected with the drawing-rolls as that the onelever may beacted upon in advance ot' the other, or both simultaneously, essentiallyas herein set forth.
